What is the charge on a proton?Sub-atomic Particles:An atom is composed of three different particles that are known as sub-atomic particles. These are neutrons, protons and electrons. The former two are present inside the nucleus. While, the electron is keep revolving around the nucleus....
An atom of gold is bigger and heavier. Split it open and you'll find 79 protons and 118 neutrons in the nucleus and 79 electrons spinning round the edge. The protons, neutrons, and electrons in the atoms of iron and gold are identical—there are just different numbers of them. In ...
Anelementis a substance that cannot be separated into simpler substances by chemical means. An element consists of anatomwith a unique combination ofprotons,neutrons, andelectrons. For example, the element hydrogen has one proton, one neutron, and one electron. We cannot use chemical methods to ...

Gold is an element on the periodic table of elements with an atomic number of 79, meaning there are 79 protons in the nucleus of a gold atom. Technically, the elements are arranged by their mass but the proton number and mass are directly related....
Protons have slightly less mass than the neutrons in the nucleus, but they are 1,836 times more massive than electrons. The actual mass of the proton is 1.6726 x 10^-27 kilograms, which is a very small mass indeed. The symbol "^-" represents a negative exponent. This number is a deci...
What is the atomic number?Atoms:Atoms are the basic unit of matter. Each atom has a dense nucleus composed of neutrons and protons. It also has a less dense outer electron cloud. Neutral atoms contain the same number of protons and electrons, which are positively and negatively charged, ...
